The moon will enter total eclipse at 9:41 p.m. on January 20th, 2019. It will end an hour and two minutes later, an unusually long eclipse, and the first one in three years that the United States has been able to see fully.

The Blood Lunar Moon is so eerie in appearance, however, that it has sprouted some unusual superstitions. In ancient Mesopotamia, it was theorized that a blood moon prophesied a great tragedy.
